    I am upgrading my head unit in my A3 8p, do I need one with a amp/sub connection for the standard amp/sub or is it all in the same connection??

    Aftermarket. Don't really see the point in upgrading oem coz it's not really that good anyway

    If your getting an aftermarket unit then you will need an adapter harness to convert the Audi wirings to the iso standard which will come with the connections you need to get the speakers all working. Go for the connects2 harness as that is the easiest to install and gets the most function without having to do a silly amount of wiring.

    If you want your aftermarket head unit to turn on and off when you turn your ignition on/remove the key, then you may need an ignition positive wire putting in from your fuse box. . Also depending on what OE audio setup you have (full bose or rear amplified) will determine which adapter you need to operate all the speakers in your car. Also you will need an aerial booster. the adapter and booster need connecting to a remote live + off your stereo . . . Fun work:yahoo:

    you dont need to do that when you use the Connects2 wiring harness... it handles that all for you.

    mmm that looks like an easier option . . i used the autoleads one . .works but doesn't include the aerial booster .

    Does the connects2 harness turn on/off the head unit when turning ignition on/removing key?

    yep!
    as well as giving you the steering wheel controls (when using hte right patch lead), ties into the reverse gear for rear view cam, allows muting of the stereo and even video in motion
